CURTAIN-POLE JOINT.

sPECIFICATION forming part of Letters Patent No. 333,476, dated December29, 1885.

Application filed November 16, 1885. Serial No. 182,925. (No model.)

To all whom it may concern:

Be it known that I, JosEPH MUNGER, of Waterbury, in the county of NewHaven and State of Connecticut, have invented a new Improvement inCurtain-Pole Joints; and I do hereby declare the following, when takenin connection with accompanying drawings, and the letters of referencemarked thereon, to be a full, clear, and exact description of the same,and which said drawings constitute part of this specification, andrepresent, in

Figure l. a perspective view; Fig. 2, a vertical central section; Fig.3, a perspective view of the plate and shanks detached; Fig. 4, amodification in construction of the plate and shanks.

This invention relates to an improvement in the connection between theparts of the pole employed over windows from which ourtains aresuspended, and are commonly called curtain-pole joints, and is animprove ment on the invention for which Letters Patent of the UnitedStates, No. 327,834, were granted October 6, 1885, to the assignees inthis application. That invention consisted in a shell, substantiallycircular in horizontal section, having a screw fixed at one point,projecting radially therefrom and in the plane of the said horizontalsection, and also constructed with a circumferential slot extendingpartially around said shell opposite the fixed screw and in the saidhorizontal plane, combined with a ring within said shell, having asecond screw rigidly fixed to it and projecting radially therefromthrough said circumferential slot and in the same plane as the otherscrew fixed to the shell. In such construction the shell and ring arenecessarily made from light metal, and form avcryslight support for. thescrew.

The object of this invention is to avoid this difficulty; and itconsistsin the construction, as hereinafter described, and particularlyrecited in the claims.

A represents the one part of the shell, and B the other part, whichtogether form a hollow shell, preferably of spherical shape. The saidpart B is constructed with a circumferential slot, at.

Within the part B a plate, C, is rigidly fixed in the plane of one edgeof the slot at,

and is constructed with a rim, 6, the said rim cut away for a distancecorresponding to the length of the slot a.

On the rim 1) and opposite the slot a screw or equivalent shank, d, isfixed, projecting radially through the shell, and in a plane parallelwith the plate C.

To the center of the plate C is pivoted a second shank or screw, 0,which extends radially through the slot a in the same plane as the fixedshank d, and is adapted to swing upon its pivot through said slot, sothat the poles, when secured to the shanks, may be turned to any desiredangle to each other, but held in the same plane.

The rim b may be omitted and the shank d secured to the plate 0, asshown in Fig. 4.

The plate 0 may be constructed from any strong material, as iron, and asit supports the shanks independent of the shell, the shell may be ofvery light material and of any desired form, it serving only as a coverand ornament for the joint.

I claim- 1. The herein-described curtain-pole joint, consisting of ashell constructed with a circum ferential slot, and a plate, C, rigidlyfixed within said shell in a plane parallel with the said slot, andconstructed wit-h a rim, .said rim cut away corresponding to the lengthof the slot, combined with -one shank fixed to said rim and projectingradially through the shell in a plane parallel to the plane of theplate, and a second shank pivoted to the said plate and extendingradially through the slot in the same plane as the fixed shank,substantially as described.

2. A curtain-pole joint consisting of a shell constructed with acircumferential slot and a plate, C, rigidly fixed within said shell ina plane parallel with said slot, combined with one shank fixed to saidplate and projecting radially through the shell in a plane parallel tothe plane of the plate, and a second shank pivoted to the said plate andextending radially through the slot in the same plane as the fixedshank, substantially as described.
